Safety instructions
Ensure that the amplifier is isolated from its supply before making or altering
any connections.
Line voltage selection
The unit is set for use on 100V line systems.To convert to 50V line,detach the rear panel
by unscrewing the six screws and turn it over to expose the line transformer.The primary
tappings can then be changed by moving the push-on connector to the 50V position (see
figure 2). Replace the rear panel and screw it into position after making the required
change.
Line connection
Connect the line input to the spring terminals at the rear of the loudspeaker (see figure
4). Reconnect the amplifier after all the speakers in the PA system have had their output
levels set and all connections have been made.
Note: Before switching on, check that the total output (watts), set on all speakers in the
system, does not exceed the maximum output of the amplifier.
